1. 1. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast

   University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

   Author : Anna Hagberg; Andreas Andersson; [2023]
   Keywords : Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

   Abstract : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. READ MORE

3. 2. Carbon Capture and Storage : And the Possibilities in Sweden

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Risha Chowdhury; Sofie Malmberg; [2023]
   Keywords : Bio-Carbon Capture and Storage Bio-CCS ; Carbon Capture and Storage CCS ; Carbon Capture and Utilisation CCU ; Carbon Dioxide CO2 ; Climate Change; Climate Policy; Costs regarding Carbon Capture and Storage; Direct Air Capture DAC ; Geological Storage; Greenhouse Gas es GHG ; Policy regarding Carbon Capture and Storage; Bio-Carbon Capture and Storage Bio-CCS ; Carbon Capture and Storage CCS ; Carbon Capture and Utilisation CCU ; Koldioxid CO2 ; Klimatförändring; Klimatpolitik; Kostnad för Carbon Capture and Storage; Direct Air Capture DAC ; Geologisk lagring; Växthusgas er ; Reglering för Carbon Capture and Storage;

   Abstract : The Paris Agreement aims to limit global warming to 1.5 degrees Celsius, and Sweden has set a goal toreach net-zero emissions by 2045. Carbon Capture and Storage (CCS) is one method that can reducecarbon dioxide emissions. READ MORE

4. 3. Optimization of support in rock pillars between two parallel tunnels

   University essay from KTH/Jord- och bergmekanik

   Author : Alexander Kote; Sohaib Ishaq; [2022]
   Keywords : tunnel; rock pillar support; rock pillar stability; rock mass; stresses; arching effect; Nyckelord: tunnel; bergförstärkning; bergpelare; bergmassa; spänningar; valveffekt;

   Abstract : When two parallel tunnels are excavated under high to moderate horizontal in-situ stresses combined with minor deformations in the pillar between the tunnels, the in-situ stresses can be redistributed over the tunnels in form of two compressive arches and are transferred from the roof to the abutments of the two tunnels. At additional deformations in the pillar, a new redistribution of the stresses can occur creating one compressive arch over both of the tunnels. READ MORE

5. 4. Stress dependent flow behavior in sublevel caving mines

   University essay from KTH/Jord- och bergmekanik

   Author : Linde Mattsson; [2022]
   Keywords : level caving; Material Flow; Mining; Discrete element modeling.;

   Abstract : Sublevel caving is an underground mass mining method that utilizes the gravity-induced material flow for ore extraction. The granular flowbehavior is one of the main phenomena describing this mining method’s efficiency; therefore, a good understanding of the flow behavior is essential. READ MORE

6. 5. Development of grout for deep shaft

   University essay from KTH/Byggteknik och design

   Author : Karl Lindberg; Adam von Krusenstierna; [2021]
   Keywords : Rock injection; Grout; Shaft; Laboration; Cement; Cement mixture; Bergsinjektering; Injekteringsbruk; Schakt; Laboration; Cement; Cementblandning;

   Abstract : In tunnel engineering one of the most important factors are the groundwater flow. To solve this problem a method called grouting is commonly used. In this study grout mixes are developed based on specific requirements for a deep shaft located next to a body of water. READ MORE
